FIELD OF THE INVENTION

The present invention relates to the field of protective cases. More specifically, the invention relates to protective cases for use with different electronic devices.

BACKGROUND

Since the early 2000s there has been an influx of portable electronic devices, more commonly referred to as portable cellular phones, smart phones, small computers, and the like that are designed with a proportionally large glass viewing screen and interface areas. With technology advancing at great leaps and bounds, the internal components of these devices are decreasing in size thus making portable electronic devices very thin in design.

Since the invention of portable electronic devices, there has also been a need for carrying cases and protective cases for the portable electronic devices. These cases are made from a wide range of material including hard plastics, soft plastics, metal alloys, wood, rubber, silicone, and leather. These cases are configured to conform tightly around the devices and preferably with one or more openings at appropriate locations for operation of the device, connections for external communications, speaker openings, power supply connections, as well as head phone connections.

Unfortunately, if the user happens to drop the portable electronic device, the glass interface may break or other damage may occur even if the device is in a carrying case or protective case due to the thin nature of prior art case. Once damaged, the user can expect to spend a significant amount of time and money to get the portable electronic device's screen replaced or other damage repaired.

Additionally, cases in the prior art are only configure to secure an electronic device and are unable to secure other related items such as extra power supplies, power cords, power adapters, and the like. Further to this end, these prior art cases are unable to secure and protect documents, writing instruments, and other similar items. These cases are also limited or unable to protect electronic devices, related items, documents, writing instruments, and other similar items from moisture, dirt, atmosphere, and other contaminants.

Therefore, a need exists for novel protective cases that are able to protect devices and objects from damage such as scratches, chips, and breakage to the glass interface and other surfaces. There is a further need for protective cases that are able to secure other related items such as extra power supplies, power cords, power adapters, and the like. An additional need exists for protective cases that are able to secure and protect documents, writing instruments, and other similar items. Finally there exists a need protective cases that are able to protect electronic devices, related items, documents, writing instruments, and other similar items from moisture, dirt, atmosphere, and other contaminants.

The first layer of material may be made from an elastomer material such as impact absorbing foams, ARTiLAGE artificial cartilage foam, Poron XRD foam, other ARTiLAGE foams, other Poron foams, silicone foams, rubber foams, plastic foams, or other elastomer materials such as elastic plastics, elastic silicone, elastic rubbers, silicone rubbers, or any other suitable elastomer material. In some preferred embodiments, the first layer of material is solid in nature with no empty or dead space within its interior. In other preferred embodiments, the first layer of elastomer material may not be solid in nature and may optionally comprise textures such as ridges and grooves, and/or structures such as honey comb like pockets, spherical pockets, or any other empty or dead space, including a plurality of such spaces, within its interior and along exterior surfaces not in contact with the lid section 11 or base section 12. In further preferred embodiments in which the first layer comprises one or more empty or dead spaces, various gases, liquids, gels, foams or other compressible materials may be positioned within the empty or dead spaces.

A second layer of material is preferably in continuous contact with the first layer of material so that no empty space or dead space exists between the second layer of material and both portions of the first layer of material contacting the lid section 11 and the base section 12. The second layer is also divided so that a first portion is contacting and secured to the first layer of material joined to the lid section 11, while a second portion is contacting and secured to the first layer of material joined to the base section 12 allowing the first and second portions of the second layer to be separated when the protective case 100 is opened.

In some embodiments, the second layer of material may be substantially permanently joined to the first layer with heat bonding, chemical bonding, adhesives, fasteners or any other suitable joining method capable of securing portions of the second layer of material to the first layer of material. In other embodiments, the second layer of material may be temporarily joined to the first layer of material by being press fit together, by one or more fasteners such as Velcro, clips, clasps, and the like, or any other temporary joining method allowing the second layer of material to be temporarily secured to the first layer of material.

The second layer of material may be made from an elastomer material such as elastic plastics, elastic silicone, Smooth-on Eco flex silicone, Smooth-on Dragon skin silicone, Smooth-on Mold star silicone, elastic rubbers, silicone rubbers, impact gels or other elastomer materials such as impact absorbing foams, Artilage foams, Poron foams, silicone foams, rubber foams, plastic foams, or any other suitable elastomer material. In some preferred embodiments, the second layer of material is solid in nature with no empty or dead space within its interior. In other preferred embodiments, the second layer of elastomer material may not be solid in nature and may optionally comprise textures such as ridges and grooves, and/or structures such as honey comb like pockets, spherical pockets, or any other empty or dead space, including a plurality of such spaces, within its interior and along exterior surfaces not in contact with the first layer of material. In further preferred embodiments in which the second layer comprises one or more empty or dead spaces, various gases, liquids, gels, foams or other compressible materials may be positioned within the empty or dead spaces.

In preferred embodiments, the second layer of material may be configured to contact and secure any object including an electronic device such as a laptop computer, tablet computer, or other devices comprising electronic circuitry, and further including items that do not comprise electronic circuitry such as tools, books, weapons, art, artifacts, or any other object including a plurality of objects. The second layer of material is preferably configured to contact exterior surfaces of objects that are placed within the protective case 100 by being configured with one or more recesses 16 with dimensions substantially identical and complementary to the exterior dimensions of an object placed in contact with the second layer of material allowing an object to be press fit into a recess 16. As depicted in FIG. 3, a recess 16 is positioned in the second layer of material in the lid section 11, and a complementary recess 16 is positioned in the second layer of material in the base section 12. An object may be placed in the protective case 100 and secured in the recesses 16 when the lid section 12 is closed on the base section 12

Also in preferred embodiments, the second layer of material is of a substantially uniform thickness so that recesses 16 of a complementary shape are congruently positioned in the first layer of material to receive one or more recesses 16 in the second layer of material. The one or more recesses 16 in the second layer of material, and therefore the first layer of material, may be preferably configured to secure one or more objects positioned centrally in the interior of the protective case 100. An object may be secured within a recess 16 by being press fit into the recess 16, or with clip fasteners, straps, or any other suitable method of securing an object within a recess 16.

The depth or thickness of the lid section 11, base section 12, first layer of material, and second layer of material may be increased to provide greater protection to objects placed within the protective case 100, or decreased to decrease the weight of the protective case 100 and to lessen the protection to objects placed within its interior. In some embodiments, the lid section 11, base section 12, first layer of material, and/or second layer of material may each be between 0.05 inches and 5.0 inches in thickness.
